On my nails is China Glaze Dope Taupe, from the Fall Rebel collection, you can see the full line of polishes HERE!
When you open it there's a little scrubby pad in there.
|Sephora solid brush cleaner
This is how I dry my brushes, I usually shake them out really well and lay them flat with the bristles hanging over an edge.
This soap retails for $14 at Sephora, I purchased it myself for use (and review!) I also use Real Techniques brushes and sponges, also purchased by me.
